Don't have an answer about your mapping question, but I've been looking at this gps as well and was just wondering where you found the smoking deal?!?
I bought the Washington / Oregon Topo sd card ( called 24K ) , it was like $ 89. It just installs in seconds & is very detailed. My buddy down loaded software & is pretty detailed . His takes longer to draw the map & update than mine does. He likes my mapping a lot better when we compare. Mike
We have used these for the past two years and I really enjoy the functionality of an all in one unit. I bought the garmin topo software for the US and chose the areas I wanted. My father in law bought the preloaded chip. For some reason the topo maps on the preloaded software is better. His showed more roads and detail than mine. If other people in your party are using the rhinos I would definitely recommend them.
